"FLOOR coNsTRUcrroN Application led March 14, 1930. Serial No. 435,690.

This invention relates to floor construction, and has special reference to oors comprising solidified plastic material,`suchy as concrete.

An object of the invention is to provide an improved construction for supporting floors made of concrete and the like, and also to provide improved means for covering the corners formed by the intersections ofthe floors with the'walls and partitions of the building, so as to prevent the accumulation and deposit of moisture and dirt and other substances in and along the corners andto provide curved members covering the corners vand forming smooth surfaces from Which the moisture and dirt and other substances may readily be removed.

Another object of the invention is to provide an improved construction for supportv ing ioors and covering the corners formed by the intersection of the floors with the walls and partitions of the building to prevent water and foreign substances trombecoming lodged in the corners. By my imi proved construction, the cleaning ofthe iioors along the edges thereof and at the intersection of the iioors with the wallsand partitions of the building, and also f the cleaning of the ceilings at such intersections with the walls and partitions of the building, is greatly facilitated, thus `improving the sanitary conditions and also contributing to the desirability of this invention.

Other objects will appearrfrom the following description, reference being made to the accompanying drawings, in whichf Fig. l is a vertical sectional view showing one embodiment of the invention.

Fig. 2 is a vertical sectional view showing a diiierent form of supports for the floors.

Fig. 3 is a vertical sectional viewshowing still another form of supports for the loors.

Fig. 4 is a perspective view of the floor supporting and corner covering device shown in section in Fig. l.

Fig. 5 is a perspective view of the corner covering device shown in section in Figs. 2 and 3.

The oors l are composed of concrete or rother material suitable for this purpose.

.the flanges 6 are smooth, so

The material is laid in a plastic condition and permitted to solidify. The partition 2 may be made of sheet metal or other material as desired.

Along each wall land along the sides of each partition are located the devices which are shaped and formed to cooperate with the walls and partitions and floors to provide rounded corners at the intersection of the floors with theV walls and partitions, so as to exclude from such corners water and other substances.

In the embodiment shown in Fig. 1, these devices also cooperate with the undersurfaces of the floors which constitute the ceilings of the rooms below, so as to exclude dirt and other substances from the corners formed by the intersection of the ceilings with the building walls and partitions. If desired, the ceilings may be made wholly or partly of metallic plates 3 having their edges upturned to provide flanges 4.

Along each edge of each floor, a plate 5 is located against the building walls and against the partitions with which the floors cooperate to provide rooms. The concrete kextends to contact with the plates 5 above the edgesof the flanges 4. The plates 5 are Vof considerably greater vertical width than the thicknessfof the floors, so that the upper edges of said platesare considerably above the floors and the lower edges of said plates are considerably below the ceilings formed by the floors. The upper edges of the plates 5 are 'bent downwardly and curved laterally to provide laterally curving flanges 6 having theirv upper edgesV approximately iiush with kthe upper surfaces of the floors. Thus, these anges form curved or rounded corners covering the joints at the intersection of the Hoor .with the plates 5, and positively preventing the lodgment of dirt and other substances in said corners. The surfaces of that they may readily` be cleaned.

The lower edges of the plates 5 are bent and laterally to provide laterally curved anges 7, seating closely against the ceiling 3, w ether the said ceiling be formed of a metallic plate or not. Thus the flanges 7 prevent the lodgment of dirt within the joints formed at the intersection of the floors with the walls and partitions of the building, and facilitate the cleaning of the walls and the ceiling.

In the construction shown in Fig. 2, an angle bar is placedalong each side of the partition 8. rIhe vertical flanges 9 of the angle bars are against the partition 8 and the horizontal flanges 10 of said angle bars extend laterally l-a'w'ayV fromsaid partition. rIhe ceiling forming plates 11 are seated upon the flanges 10. Upon the ceiling form-V ing plates 11, the concrete or. other solidified plastic material is placed and smoothed to provide floors 12. Flanges 10, bearing closely against the sides ofthe. partition 8 and being impervious to moisture, prevent the lodgment of moisture and dirt within the joints or corners. The surfaces` of the partition and of the llangeslO being smooth, no difficulty is encountered in keeping the joints in a clean and sanitary condition.

Along each wall and along each 'side of each partition, a plate 13 has its lower edge extending downwardly between the floor 12 and the wall or partition, and its upper edge projecting substantially above the loor and bent downwardly and curved laterally to provide a rounded corner flange 14. The lower edge of the flange 14 extends into the upper surface of the concrete or floor material, so that the upper side of the flange is `flush with the upper surface of the floor. Thus the corners are covered and shielded, preventingthe lodginent of dirt therein and facilitating the cleaning of the floors and walls so as to keep, the premises in a sanitary condition.

-In the arrangement vshown in Fig. 3, the

metalic ceiling is omitted. The partition 15 `has its lower edge bent laterally to provide a laterally extending flange 16, theundersurface of which is flush with the under- -surface of the floor 17, which forms the ceiling'of the room below. At the opposite side of the partition, the floor 18 has its undersurface formed flush with the undersurface yof the flange 16 and with the undersun face of the floor V17, Y so that a continuous lsmooth ceiling is provided. The floors 17 7 and 18` may be constructedy of concreteV or o'her appropriate material, and the corners formed by the inter'sectionof said floors with `the walls and partitions of the building are shielded and covered by curved flanges 19 extending downwardlyv and laterally from Ldie upper edges of plates 20.. The lower edges of the plates 2O are embedded n between the building walls and partitions and lthey floors of the building .The upper edges of the'flanges 20 form curved surfaces, be-

ginning smoothly with the upper surfaces of the `floors and providing a construction which may easily be Cleaned and kept in a sanitary condition.

It is now clear that my improved floor construction is designed and adapted for use in many types of buildings.7 It is well adapted for buildings of the institutional type, though it may be used with equal satisfaction in buildings for other purposes, such as store buildings, oflice buildings, manufacturing establishments, and the lilre. The

construction Sand "arrangement may be varied otherwise than as particularly indicated in the dra-wings, and I contemplate such variations as may be desirable in the particular embodiments in which the invention is used. I do not restrict myself in any unessential respects, but what I claim and desire to secure by Letters Patent is j 1. In a building, a wall, a concrete floor,

a plate mounted between the floor and the of substances at said juncture, and a part in connection with said device extendingV and clamped between the floor and the Wall and holding said device rigidly in the position aforesaid. v j

3. In a building, a wall, a floor extending awayfrom the wall, a plate of curved form at the juncture of the wall and floor preventing accumulation of dirt and other substances in the corner formed by said wall and ysaid floor, and a portion integral with said plate and'extending downwardly and secured between said wall and said floor and holding said plate rigidly in the position aforesaid.

4. In a building, a wall, a floor extending away fromrsaid wall, a plate extending upwardly and secured between said floor and said wall, and an upwardly and laterally vcurved portion in connection with the lower edge of said plate having its edge engaging the underside of said floor and preventing the accumulation of dirt and other substances inthecorner formed by said floor andv said wall.
